It's been called the greatest synchronized sex show on earth, and only the very lucky have been witness to it. A few nights after the November full moon, corals release millions of pink bundles of egg and sperm that drift to the surface in an enormous upside-down blizzard, resembling what it must be like on the interior of a shaken snow globe. Every year, snorkelers and divers from around the world point their dive lights into the pitch-black waters of Australia's Great Barrier Reef, hoping for a glimpse of the mass spawning event. By observing spawning events and conducting experiments, marine biologist Erika Woolsey seeks to understand how warming oceans will affect the ability of coral reefs to replenish themselves and recover from disturbance, which is especially important in changing oceans.
Coral reefs are the rainforests of the ocean. They cover less than 1% of the sea floor, yet support about 25% of marine species. Unfortunately about 60% percent of the world's coral reefs are under immediate threats from climate change and localized human disturbances.
Using gorgeous images, Woolsey will talk about her adventures Down Under and underwater, and give you a front-row seat to this exotic and rarely seen world.
